If you're responsible for a commercial property, an office, school, care home, restaurant or industrial site, your gas appliances aren't optional extras. They're safety-critical equipment, and by law they need to be checked every year by a qualified engineer. The question most facilities managers and business owners actually want answered isn't whether they need commercial gas servicing; it's what a proper contract should cover so nothing gets missed.
At Spa Gas, we've spent over 25 years managing commercial gas servicing and maintenance for businesses, schools and public sector clients across the UK, so we know exactly where gaps in a contract tend to cause problems later. This guide breaks down what should be included in a commercial gas servicing contract, why it matters, and how to choose a provider you can rely on.
A commercial gas servicing contract is an agreement between your business and a heating and gas maintenance provider to look after your gas appliances on a planned, ongoing basis. Rather than waiting for a boiler to break down and calling an engineer reactively, you get scheduled inspections, servicing and support built into a single agreement, usually priced on a monthly or annual basis. Spa Gas structures this as part of our Reactive, Service & Maintenance offering, tailored to your site.
For commercial premises, this typically covers boilers, water heaters, catering appliances and other gas-fired equipment, along with the compliance paperwork that proves it's all safe to use.
Yes. Commercial gas servicing isn't a nice-to-have; it's a legal duty for anyone responsible for a workplace, rented commercial property, or public building.
Under the Gas Safety (Installation and Use) Regulations 1998, any gas appliance used in a commercial or non-domestic setting must be serviced and inspected annually by a Gas Safe registered engineer. This applies whether you own the building or lease it, and it applies to landlords letting commercial or mixed-use premises too. Operating a commercial property without a valid gas safety check is a criminal offence, and non-compliance can lead to significant fines.
At the end of a compliant service, your engineer must issue a Gas Safety Certificate (sometimes referred to as a CP12 in a commercial context). This document confirms the appliance has passed its safety checks and is valid for 12 months. It should record:
You're required to retain these certificates as proof of compliance, and many insurers will ask to see them if you ever need to make a claim.
This is where a lot of commercial contracts fall short: either they're vague about what's actually covered, or they exclude the things that matter most when something goes wrong. Here's what a comprehensive commercial gas servicing contract should include.
At minimum, your contract should guarantee a statutory annual gas safety inspection, with the Gas Safety Certificate issued and provided to you (or your compliance team) at the end of every visit, not left to chase up afterwards.
A proper service goes well beyond a quick visual check. Your engineer should be examining and cleaning the internal and external components of the boiler, checking for leaks, corrosion, ventilation issues and wear, testing combustion performance and pressure, and confirming that integrated safety devices are functioning correctly. If any other gas appliances are on site, these should be checked to the same standard during the same visit.
Beyond the single annual visit, look for a contract that includes planned preventative maintenance, scheduled checks throughout the year designed to catch small issues (a failing component, a pressure drop, early corrosion) before they become a breakdown. This is particularly important for buildings with heavy boiler use, such as schools, care homes and catering environments.
Clarify exactly what's included if something needs fixing. Some contracts cover labour only, leaving you to pay for parts separately; others bundle parts and labour together up to a defined limit. Make sure this is spelt out before you sign, so a repair bill doesn't come as a surprise.
A servicing contract should set out what happens when something goes wrong outside the scheduled visit: how quickly an engineer will attend, whether callouts are unlimited or capped, and whether emergency or out-of-hours cover is included. For businesses that can't afford downtime, this is often the single most important clause in the whole agreement.
Commercial sites rarely rely on a boiler alone. A well-rounded contract should be able to extend to other gas and mechanical systems on site, including commercial catering equipment, water heaters, air conditioning and building controls, so you're not juggling separate contracts and separate engineers for each system.
Every visit should be backed up with a clear written report: what was checked, what was found, what (if anything) needs attention, and the urgency of any required work. This matters for two reasons: it protects you if you ever need to demonstrate due diligence, and it gives you something concrete to pass up to management when repairs need approving.
This should go without saying, but always confirm the engineers carrying out your servicing are Gas Safe registered. Without it, your certificate isn't valid, and you have no guarantee the work has been done to the required standard.
Beyond ticking the compliance box, a well-structured contract genuinely pays for itself:
By law, commercial gas appliances must be serviced at least once every 12 months. However, sites with heavy or continuous boiler use, such as schools, hospitals, care homes, hotels and commercial kitchens, often benefit from servicing twice a year, both to reduce the risk of mid-term breakdowns and to keep equipment running at peak efficiency. Your servicing contract should be tailored to how your building actually uses its gas appliances, not just set to the statutory minimum by default.
When comparing providers, look beyond the headline price. Check that they're Gas Safe registered, ask exactly what's included versus what's chargeable as an extra, confirm response times in writing, and ask whether the contract can flex as your business or site changes. A provider with public and private sector experience, including schools, NHS trusts, local authorities, hospitality and industrial clients, will typically have a better handle on the compliance and reporting standards larger organisations expect.
A gas safety inspection focuses specifically on the statutory safety checks needed to issue a Gas Safety Certificate. A full gas service is more thorough, including cleaning, performance testing and preventative checks alongside the statutory inspection.
Yes, most commercial gas servicing contracts are designed to cover all the gas appliances on a site in a single visit and a single agreement, including boilers, water heaters and catering equipment.
Operating without a valid certificate is a legal offence and can result in a significant fine. It also risks invalidating your insurance. Your servicing contract should ensure a new inspection is booked well before the current certificate expires.
Spa Gas has been managing commercial gas servicing, maintenance and compliance for businesses, schools and public sector organisations for over 25 years. We'll build a contract around how your site actually operates, covering annual servicing, planned preventative maintenance, repairs and compliance reporting in one straightforward agreement as part of our full range of services.
